Description
Technical field
The present invention relates to the manufacturing approach of cable, especially relate to a kind of method of manufactured copper alloy cable.
Background technology
Copper and alloy thereof are because of having excellent conducting performance, heat conductivility, anti-fatigue performance, chemical stability and intensity and being easy to characteristics such as manufacturing; Had application widely in industries such as electric power, machinery, electronics, traffic and the energy, become the important electron metal material.Along with fast development economic and science and technology, to used copper alloy with high strength and high conductivity demands for higher performance in field such as contact Wire for High-Speed Electric Railway, extensive integrated circuit lead frame and electrode materials.Yet, owing to the physical characteristic of copper alloy self causes being difficult to take into account simultaneously its intensity and conductivity, final acquisition intensity and all good copper alloys of conductivity of being difficult to.
At present, mainly solve the contradiction of copper alloy high strength and high conductivity through alloying and composite material method.Though the composite material method can obtain the superhigh intensity copper alloy, its complicated process of preparation is difficult for large-scale production; Alloying preparation technology is simple than the former, is widely used at present, but still has some problems, costs an arm and a leg like other composition that is added, and antiacid alkali resistant ability is lower, non-refractory, and conductance still can not satisfy the demands in some field.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of copper alloy cable that overcomes above-mentioned prior art defective.
The method of the prepared a kind of manufactured copper alloy cable of the present invention is to comprise the element of following weight percentage:
Ni 0.98-1.14％

(2) pull slag out after, add Ti, W, Mg, the back tapping casting that stirs, and the control furnace temperature is at 1320～1370 ℃,
(3) adopt the semi continuous casting, use nitrogen protection during casting;
(4) under 100-120 ℃, be drawn into wire rod, then wire rod be heated to 3-4 hour oil of quenching of 700-820 ℃ of insulation, Ageing Treatment was carried out in insulation in 1-1.5 hour under 500-520 ℃ of temperature again; Gained cable wire technical characteristic is: HRB >=75, IACS >=75%.
